Rakuten Software Engineer interview questions

The interview process was very straightforward and rather simple. The questions didn't seem too difficult, but the interviewers were all very pleasant and easy to talk to throughout the interview. However, the last interviewer (VP or lead of some kind, can't remember the exact title) was a little terse and seemed condescending at times, so the last interview was not as pleasant but still pretty lax as we only talked about very general things and personal experiences.
